ASP.NET MVC4 DataAnnotations Validation on Models acting very strange - validating all fields even when I only specify one field to be validated

To keep this real simple, I have a model that has just one Required attribute (just on the Name). My View only has one @Html.ValidationMessageFor that's tied to the Name. When I click Save on the View when nothing is filled in, all fields come back as required. If I fill in the Name field, the remaining fields come back as required. I really need some help figuring out why this is:

public class KeyActive
{
    [Key]
    public int Pk { get; set; }

    [Required(ErrorMessage="Name of filler is required.")]
    [Display(Name="Name:")]
    public string Name { get; set; }

    [Display(Name = "Capsule 00 Pack Stat:")]
    public int PackStat00 { get; set; }

    [Display(Name = "Capsule 0 Pack Stat:")]
    public int PackStat0 { get; set; }

    [Display(Name = "Capsule 1 Pack Stat:")]
    public int PackStat1 { get; set; }

    [Display(Name = "Capsule 3 Pack Stat:")]
    public int PackStat3 { get; set; }

    public string CreatedBy { get; set; }
    public DateTime CreatedDate { get; set; }
    public string ModifiedBy { get; set; }
    public DateTime ModifiedDate { get; set; }
}

Here's my View:

<div data-role="fieldcontain">
    @Html.LabelFor(model => model.Name)
    @Html.EditorFor(model => model.Name)
    @Html.ValidationMessageFor(model => model.Name)
</div>

<div data-role="fieldcontain">
    @Html.LabelFor(model => model.PackStat00)
    @Html.EditorFor(model => model.PackStat00)
</div>

<div data-role="fieldcontain">
    @Html.LabelFor(model => model.PackStat0)
    @Html.EditorFor(model => model.PackStat0)
</div>

<div data-role="fieldcontain">
    @Html.LabelFor(model => model.PackStat1)
    @Html.EditorFor(model => model.PackStat1)
</div>

<div data-role="fieldcontain">
    @Html.LabelFor(model => model.PackStat3)
    @Html.EditorFor(model => model.PackStat3)
</div>

Finally, when I fill out the form and click Save, here's what I get:

enter image description here

It's acting like every field is required- when I fill in Name, and leave everything else blank, it won't let me submit it because it seems to think the other fields are also required. I really need some help figuring out if there's another place that I'm not seeing that performs validation, or what I'm doing wrong here!! Thanks.

Could it be because your ViewModel is using int instead of a nullable value: 

public Nullable<int> PackStat00

or

public int? PackStat00

Right now, there's no way to store a null value in your view model for those fields.
